Abstract: A message-based communication system includes a communication link having an associated message version. A first device is coupled to the communication link. The first device is configured to communicate messages across the communication link using the message version associated with the communication link. A second device is also coupled to the communication link. The second device is configured to communicate messages across the communication link using any of several different message versions. A message version controller is also coupled to the communication link. The second device includes a link status database that is used to store information regarding communication links coupled to the second device.

Abstract: A system is provided for allocating resources in a call center. The system identifies a record associated with a resource in the call center. The record includes an attribute associated with the operation of the resource. The system controls the operation of the resource in response to the attribute contained in the record associated with the resource. The record associated with the resource is modified in response to a resource change request. The resource change request may be generated by a host coupled to the call center or by a device contained within the call center. The modified record provides a different set of permitted activities for the associated resource. A particular record may contain multiple attributes associated with the operation of the resource.
